Specifically, the tongue assembly 21 includes a fastener 211, a fourth protrusion 2111 protruding on the fastener 211 to limit the displacement of the tongue 1016, and is connected to the fastener 211 The third driving member 212 can drive the fastening member 211 to rotate to a preset position. In this embodiment, the fastener 211 at the preset position is parallel to the top surface of the packaging box 101 (the plane where the box opening 1015 is located). The fastening member 211 is composed of a plurality of long rods. In this embodiment, three long rods are connected perpendicularly to each other. When the fastening member 211 is in the preset position, the respective long rods of the fastening member 211 are just on the surface of the main cover 1012. Fitting means that the fastener 211 needs to be matched with the main cover, and at the same time, the weight of the tongue assembly 21 can be ensured to be lighter, and the strength requirement for installation can be reduced. The fourth protrusion 2111 is provided at one end of the fastener 211 and protrudes toward the packaging box 101. The length of the fourth protrusion 2111 is set according to the length of the tongue 1016 folded out by the tongue folding assembly 1. After the tongue 1016 is bent out of the tongue 1016, the first base plate 11, the second base plate 12, and the pressing member 13 are all returned to their positions, and the tongue 1016 is separated from the pressing member 13, the first base plate 11 and the second base plate 12. When it is restricted, it tends to return to its original flat state. At this time, the tongue 1016 recovers in the opposite direction of the bending direction so that the bending angle becomes smaller. Here, the fourth protrusion 2111 is used to restrict the recovery of the tongue 1016. That is, the restriction tongue 1016 is released from bending. The number of the fourth protrusions 2111 can be set to be multiple, and the fourth protrusions 2111 are spaced apart from each other, or it can be set as a fourth protrusion 2111 opposite to the middle position of the tongue 1016, according to the needs of the tongue 1016 . By inserting the tongue 1016 into the packaging box 101 in the above manner, it can be ensured that when the fastener 211 inserts the tongue 1016 into the packaging box, the situation that the tongue 1016 is not outside the packaging box 101 will not occur, and the third driving member 212 It is preferably a rotary cylinder, which is low in cost and easy to control.

More specifically, as shown in FIG. 8, the box sealing device 2 further includes a limiting component 22 disposed on the side of the first base plate 11 of the flap assembly away from the pressing member 211, and the limiting component 22 includes a limiting member 221 and a fourth driving member 222 connected to the limiting member 221 to drive the limiting member 221 to move away from or close to the tongue assembly 21. During the operation of the tongue 1016, because the packing box is loaded with materials, there may be a small amount of deformation. At this time, the tongue 1016 may not be effectively aligned. The fourth driving member 222 moves the limiting member 221 to the main panel of the packing box. The 1012 fits and applies a certain pressure or displacement to it, which effectively guarantees the overall flatness of the packaging box when the insert tongue is inserted, thereby ensuring the effectiveness of the insert tongue 1016.
